Problems solved by technology
[0003] However, the setting of the hole-digging area will cause the side of the organic light-emitting diode device layer to be exposed to the air, causing water and oxygen in the external environment to easily enter the display area from the hole-digging area, resulting in the risk of packaging failure of the display panel.
[0004] Therefore, it is necessary to provide a new display panel and display device, improve the packaging effect of the OLED display panel of the camera under the screen, and solve the problem of failure of the display panel packaging in the prior art

The invention discloses a display panel and a display device, and relates to the technical field of display. The display panel comprises an opening area, a non-display area and a display area, the non-display area comprises a first non-display area, the first non-display area surrounds the opening area, and the display area surrounds the first non-display area. The display panel comprises a substrate, a thin film transistor array layer and a light-emitting functional film layer, the light-emitting functional film layer comprises a common layer located in a first non-display area and a displayarea, and the display panel further comprises at least one partition groove located in the first non-display area. An opening of the partition groove faces the light emitting direction of the displaypanel, a film layer where the partition groove is located is located at the side, close to the substrate, of the common layer, and the common layer is disconnected at the partition groove. A reflecting layer is located between the film layer where the partition groove is located and the substrate and is reused as the bottom wall of the partition groove, or a preset distance is formed between the bottom wall of the partition groove and the reflecting layer. The partition groove can prevent the water and oxygen from invading, and the reflecting layer can assist in forming the partition groove.
Description
technical field [0001] The present invention relates to the field of display technology, and more specifically, to a display panel and a display device. Background technique [0002] Organic Light-Emitting Diode (OLED) display panels are widely used in the field of display technology due to their many advantages such as active light emission, high contrast, no viewing angle limitation, and flexible display. At present, in order to increase the screen-to-body ratio of flexible OLED display panels and enrich their use functions, the non-display area on the display panel is compressed smaller and smaller, and a hole-digging area is usually set in the display area to place things such as cameras, etc. Photosensitive original. [0003] However, the setting of the hole-digging area will cause the side of the organic light-emitting diode device layer to be exposed to the air, causing water and oxygen in the external environment to easily enter the display area through the hole-dig...
